This'invention relates to improvements in vaginal syringes.

The primary object of this invention is the provision of a vaginalsyringe embodying 5 means to provide a lateral and preferably rotarycleasing spray, and including a novel air duct arrangement to permit thedrawing of air into the vaginal canal as the syringe is being withdrawn,for the purpose of preventing the displacement of the womb incident tosuetion created by such withdrawal.

Other objects and advantages of thisinvention will be apparent duringthe course of the following detailed description. 1

In the accompanying drawing, forming a part of this specification, andwherein similar reference characters designate corresponding partsthroughout the several views,

Figure 1 is a side elevation, partly in sec-s tion, showing details ofthe improved syringe. Figure 2 is a fragmentary sectional view takenthrough the forward part of the syringe, showing novel features thereof.

Figure 8 is a fragmentary side elevation of the nozzle end of thesyringe.

Figures at and '5 are cross sectional-views taken substantially on theirrespective lines in Figure 3 of the drawing. 1

Figure 6 is a detailed view of the rear end construction of the maintube.

In the drawing, wherein for the purpose of illustration, is shown only apreferred embodiment of this invention, the letter A may generallydesignate the improved syringe,

-; which may consist of a main tube 13; having a detachable andcollapsible rubber bulb C supported at one end thereof, and a novel.

nozzle D supported at the opposite end thereof. A novel air duct ortube'E is provided 40 within the main tube in a cooperative rela tionwith respect to the nozzle D, and a resilient guard member F supportedat the end of the main tube B adjacent the bulb C.

The main tube B is preferably slightly arcuate as to its length, and itis formed of die cast hard rubber, or enameled aluminum or any approvedmaterial. It provides a relatively large passageway 10 which extendstherethrough from end to end. At its forto ward end the passageway 10 isentirely open,

the tube B is provided with an annular bulb retaining flange 12,andin'spaced relation with respect to the annular flange 12 is alsoprovided with an annular guard and bulb retaining flange 13 which isrelatively wide and preferably provided with a forward bevel edge 14.The passageway lOis entirely open.

at the rear end of the main tube B, and in fact is provided with aflaring mouth 15 facing the bulb C. The bulb C is preferably of redcollapsible rubber, or analogous material, and may be of any approvedshape. The same is closed at one end andat the opposite end 5 thereof itis providedwith a main tube at-.' taching tubular shank16, adapted tobeexpanded over the rear end of the main tube B, into gripping relation inthe annular channel between theannular flanges 12 and 13. with theforward edge 17 abutting against the rear edge of the annular flange13,- as illustrated in the drawing.

The soft rubber guard F is of hollow frustoconical formation, inaccordance with 75. conventional syringe guard construction, and at theforward reduced end 20 thereofthe samehas a passageway 21 within whichthe main tube 13 is received. The guard F from thisend 20 slopesrearwardly with an increasing diameter, and the same is provided with achamber 22 thereinf The forwardend 20 of course abuts against thebeveled edge 14 of the annular flange 13 of the tube'B, and thus limitsthe movement of the guard F towards the bulb C. Theguard F extendsrearwardly to receive the forward end of the bulb C in the pocket 22thereof, in a spaced relation, and the outer flange 13 is sufficiently.wide to. entirely space the shank 1 6 annularly from 99- the internalperiphery of the pocket'22 of the guard F, as illustrated in Figures 1and 2 of the drawing. This is important, since a lateral opening12d isprovided in the maing tube B through which a right angled air inlet end25 of the vent tubeE extends, toreceive air from the pocket 22 forwardlyof the for- 1 ward edge 17 of the bulb shank 16, andthe passageway. ofthis airtube E must not be obstructedwithin the pocket ice The air tubeE is preferably of aluminum or analogous material, and the same is ofrelatively small diameter, extending along the passageway 10, and onlypartially fillino the same. The tube E includes the main body portion30, which extends along the passageway 10, and as abovementioned thesame is right angled at 25, at the rear end thereof, and extends throughthe opening 24 of the main tube B, andhas an inlet opening 31 to thepassageway 32 of the tube E. The end of the tube portion 25 is laterallyflanged at the exterior of the main tube B to retain the said air tube Einposition'iat-the guard F. The vent tube E extends beyond .the forwardedge 11 of the main tube B, and at its forward end is open, and the tubeE is outwardly provided with a retaining flange 35. Just slightly1nwardly of the retaining flange 35' the tube E is preferably annularlyoutwardly bulged at 36 to provide an anchor for the nozzle D.

The nozzle D is preferably of semi-elliptic or parabolic formation, andthe same is hollow and provided of hard rubber, or any approved materialsimilar to the main tube 13. I The nozzle D is largest at its rear endadgacent the forward end of the tube B, and the nozzle D is providedwith a pocket 37 therein, opening at its rear end, and of the same sizeas the pockets or passageway 10 of the main tube B. A. plurality ofanchor pins 89 are connected in the forward end of the main tube B andthe rear end of the nozzle D to anchor the nozzle D in alignmentforwardly of the main tube B, with the passageway 10 and the pocket 37in aligning relation. In

this position the front edge of the tube B is in annularly spacedrelation with the rear edge of the nozzle 1) to provide an annular space42 through which the cleansing fluid may flow radially of the nozzle andtube. The nozzle is provided with a rear beveled surface parallel withthe bevel edge 11 of the tube B, to deflect the cleansing fluid slightlyrearwardly as it passes into the annular space provided with an openingwithin which of the bulb C will flow laterally through the annular way42 and thence forwardly through the fluid grooves 4a, to gently andthoroughly cleanse. If properly inserted the front end of the vent tubeE will be closed when the syringe tube B is fully inserted. In thisconnection it should be noted that the tube E does not provide a ductfor return of the cleansing fluid. The same is relatively small, and thesole function of the same is to vent air to a point forwardly of thenozzle D as the syringe tube is being withdrawn from the vaginal canal,to relieve the suction created incident to such withdrawal.

Various changes in the shape, size, and arrangement of parts may be madeto the form of invention herein shown and .de-

scribed, without departing from the spirit of the invention or the scopeof the claims.
